QA1 MCOM30 MCOM Series Metric Spherical Bearing 52100 Steel 30mm Bore

The QA1 MCOM30 is a metric COM Series plain spherical bearing engineered for a wide range of commercial and performance applications. Featuring a 30mm bore diameter, this bearing is built to handle demanding radial and angular loads with precision and durability.

What sets the MCOM Series apart is QA1's use of alloy/chromoly steel for the race — a significant upgrade over standard carbon steel races found in many competing COM-series bearings. This material choice delivers superior wear resistance and longer service life in high-stress environments.

Key Features:

• Ball: 52100 bearing steel, heat treated, precision ground, and hard chrome plated for surface hardness and corrosion protection
• Race: Alloy/chromoly steel (stainless steel available at manufacturer's option), heat treated and protective coated for corrosion resistance
• Bore Diameter: 30mm metric bore
• Construction Style: Metric
• PTFE Lined: No — standard grease-lubricatable design
• Designed for use in suspension links, control arms, panhard bars, and similar high-load pivot points

The MCOM30 is a direct-fit metric spherical bearing suited for motorsport, performance suspension fabrication, and industrial motion control applications where reliability and precise articulation are required.
